Means are provided to s ide the collar around the flanges and in contact therewith, With the folded edge in the groove h, and for this urpose I prefer to use an endless belt 0, whic passes over the grooved pulleys p and under the idler-pulley g. The pulleys p are mounted on shafts which are rotatably sup orted in bearings 1" on the standard I), eacfl of these shafts having a gear 8 fixed thereon, which meshes with another ear t, su ported on the driving-shaft u, on w 'ch is a belt-driven pulley v or other equivalent means for rotating the shaft. The belt 0 is so disposed that it will run under and partially around the flange g in its passage from one pulley p to the other and as shown in Fig. 4. At that point is Where the mouthpiece joins the flanges g g the pulley p is located in such position that the elt 0 will receive between it and the outer surface of the flange g that part of the collar which extends beyond the edge of the flange g. The idlerpulley g is supported on the shaft w, having the posts :0 t ereon extending downwardly into the socketed standards y, said posts being provided with s iral springs 2, whereby suitable tension may e maintained on the belt 0. Preferably the socketed standards 1 are made adjustable, as shown in Fig. 1, whereby the tension of the springs .2 may be re ulated to compensate for any stretching of t e belt which may occur. The mode of efiecting this adjustment of the standards is as follows: The osts 00 extend downward through the stan ards y, which are threaded on the supports y, the (parts 1 being counterbored from the lower en to provide space for the springs .2 between the top of the standards 1 and the enlarged heads at on the lower end of the posts 00. When the standards y are screwed downward onto the supports 3 the springs z willbe 'compressedand the. tension varied: on

While this construction-is. thought to-be best suited forthepur ose-"as. a meanstoslideth collar around the. anges. of the drum mother means may be employedin" place thereof, if desired. It has been found -advantag.eous,, I --however', to hold theoollar closetothe flange;

, and-slide it therearound' bymeansof the pres gzsureapplied by-a belt. -In operating this'machine aflat collar as it. issues-from the. ordinary ironing-rolls, istaken f by the operator and the folding-line through the center thereof is passed over .theendof a pipe from; whichissues a-jet of, steam under ow pressure, whereby .the starch along this; line'may. besoftened; .3. The. sides ofthe collar V at one end thereof are then folded together,

and this end is introduced into the open end of the mouthpiece j, the folding edge of the collar being pressed back against the rear wall of the mouthpiece and the collar being pushed forward meanwhile toward the point where the belt 0 runs onto the flange g, and the forward end of the collar being cau ht in said belt the collar is quickly slid around the flange g, the belt pressing the two sides together and continuing the folding operation, the moistened folded edge of the collar being crowded into the groove h, and by the time the rear end of the collar passes out from under the delivery end of the belt 0 the forward end of the collar has been rolled up within the chamber inclosed by the flange g. The collar, owing to the formation of the end wall of said chamber and the general spiral direction it has followed in the groove h, will be wound in helical form, as shown in Fig. 5,

and may be grasped by the operator as soon as released by the belt and withdrawn from said central chamber of the drum. All of the surfaces over which the collar has passed being heated by means of the steam-chamber d or other suitable means, the moistened starch along the folded edge thereof will have become set again, when the rolling operation is finished. The collar therefore in issuing from the machine is ready for packing, and at no point durin the operation has the folding-line of the col ar been subjected to any direct pressure. This, it is believed, is an entirely novel feature.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. In a collar-folding machine, a stationary helically-disposed drum and a flexible device to slide the collar around and in contact with the drum, and means to heat the latter.

2. In a collar-folding machine, a helicallydisposed stationary drum, and flexible means toslide the collar therearound, there bein a rooveat thebase of said drum to receivet 1eolded edge .of the: co ar, and me t h the drum.
